C#中改变字体和DataGridView中的数据导出的方法
C#中改变dgv中的字体很简单的，只需要一个简单的方法，就OK了
View Code
1
//
改变字体
2
private
void
btnFont_Click(
object
sender, EventArgs e)
3
{
4
try
5
{
6
FontDialog fontDialog
=
new
FontDialog();
7
fontDialog.Color
=
dgvHistroy.RowTemplate.DefaultCellStyle.ForeColor;
8
fontDialog.Font
=
dgvHistroy.RowTemplate.DefaultCellStyle.Font;
9
fontDialog.AllowScriptChange
=
true
;
10
if
(fontDialog.ShowDialog()
!=
DialogResult.Cancel)
11
{
12
dgvHistroy.RowTemplate.DefaultCellStyle.Font
=
fontDialog.Font;
//
将当前选定的文字改变字体
13
}
14
DataTable ds
=
(DataTable)dgvHistroy.DataSource;
15
dgvHistroy.DataSource
=
null
;
16
dgvHistroy.DataSource
=
ds;
17
ds.Dispose();
18
}
另外再导出dgv中的数据也是如此，暂且放在这里，以后用了会很方便的，呵呵
